6 Chapter 1 - Product Overview Features Supports IEEE802.11n and IEEE802.11b/g With support for Wireless-N, Wireless-G, and Wireless-B standards, the AirStation can transfer data to and from all standard 2.4 GHz wireless clients. Supports WDS WDS bridging allows multiple units to operate in a bridged network for extended coverage. Dual speed mode Dual speed mode makes wireless transmission faster by using 2 channels, allowing 150 Mbps data transmission. Support AOSS and WPS Both AOSS (AirStation One-touch Secure System) and WPS (Wi-Fi Protected Setup) are supported. These automatic connection standards make connection with compatable wireless devices easier. Security Features The AirStation is equipped with the following security features: AOSS WPS WPA-PSK (TKIP/AES) WPA2-PSK(TKIP/AES) WPA/WPA2 mixed PSK WEP(128/64 bit) Privacy Separator MAC address access restriction Deny Any Connection/SSID stealth Web configuration interface with password Firewall with easy rules Automatic Channel Selection Monitors wireless interference and automatically assigns the clearest, best channel.

7 Chapter 1 Product Overview Initialization To restore settings back to the factory defaults, hold down the Reset button on the bottom of the unit. Browser Based Administration This unit can be easily configured from a web browser on your computer. Air Navigator CD Requirements The AirStation wireless router and access point works with most wired and wireless devices. The automatic installation program on the CD requires Windows 7, Vista or XP to run. Client Manager software is included for Windows 7, Vista and XP. The use of other operating systems may require that the AirStation be manually configured from a browser window. 150 Mbps High Speed Mode 150 Mbps is the link speed of WCR-GN when using Wireless-N mode. It represents actual wireless data speeds, including overhead. Because the overhead is not available for user data transfer, usable wireless throughput will be substantially slower.

Priority The following priorities may be applied to individual transmission packets: (Highest) 8, (High) 4, (Normal) 2, and (Low) 1. From the queue, these packets are processed in order of priority. CWmin, CWmax The maximum and minimum value of the contention window. The contention window is used in the frame collision avoidance structure performed in IEEE802.11, and generally the smaller the value in the window, the higher the probability that the queue obtains the right to send. AIFSN The interval to send frames. The unit of the AIFSN is a slot, just as the window defined by CWmin and CWmax is. The smaller the interval of sending frames, the faster the algorithm can restart. As a result, the priority of the queue is higher. TXOP Limit The period of time that the queue can use after obtaining the right to send. The unit is 32 ms. The longer this time, the more frames can be sent per right to send. However, the queue may interfere with other packet transmissions. If TXOP Limit is set to 0 (zero), only one frame can be sent per right to send. WCR-GN User Manual 50
